To all whom t may concern:

Be it known that ll, Lrs'rnn A. VVEIRNERY, a citizen ot the UnitedStates, residing in Brooklyn borough. in the county of Kings, city andState ot New York, have invented certain new and usetul Improvements inType-Whiting Machines, ot which the lollowing is a specification.

lll/ly invention relates to typewriting machines, and is particularlydirected to tabulating' devices for carriages. In its preferred torni,as herein disclosed, it is applied to a lcombined column-selecting' andtabulating device 1n which. when a column key 1s depressed and a decimalkey is also depressed, the carriage is released trom its escapement, andis drawn along until arrested at the selected decimal place in theselected column.

Une object ot' the present invention is to simplify mechanism ot thischaracter, and to so arrange said mechanism that a single kind ot columnstop may be used interchangeably tor every column, and that overthrowor. rapid operation of the keys will never select the wrongr column orthe wrong letter-space in anycolumn. To bring about this result, thecarriage ot the typewriter may comprise the usual rack bar on which theusual stops are settable. Said stops may he arrangeffl to successivelyoperate a selector bar or a star wheel in such a way that the number ofsaid stops so operating said selector bar or Wheel will determine whichcolumn-selecting key shall be effective. 'llhe `first column key may loenormally operable to arrest the carriage in coperation with the decimalkeys. ils the carriage travels alongr the first stop on the carriage maymorer the selector bar or ratchet wheel to such a position that thesecond colinim-selecting key it depressed will arrest the carriage;while it said second column-selecting key is not depressed, but someother column key is depressed, the carriage stop corresponding to saidcolumn key will move the selector bar so that said other column key willarrest the carriage. To this end, the stops and counterstops may benormally so positioned that the operation ot any key does not move saidstops and counter-stops to a position where they will be ettective oneachother, but the movement ot the carriage permits said stops to shiftinto effective position.l This may be brought about by mounting thecarriage stops on a-rack bar which is so arranged Specileation of'Letters Patent.

that the paths of said stops lie normally beyond the counter-stops.l/Vhen, however, the carriage reaches the selected column, said rack barshifts so as to bring the next stop thereon into the path ot' thecounter-stop. 'llhis nent stop, therefore, arrests the carriage at thecolumn thus selected, and it said counter-stop forms one of an arraycoin- 'prisingr a decimal tahulator. said counterstop will arrest thecarriageat the selected n letter-space in the selected column.

Other tentures and advantages will here inafter appear. i

ln the accompanying drawings, Figure 1 is a perspective View ot so muchof an Underwood typewriting machine, with my in1- provenients appliedthereto, as is necessary to the understandiugl of my invention. Fig. 2is a sectional side view showinroj1 the earriage passing a counter-stopbecause the rack har on said carriage is in an ineflective position.liig. 3 is a view similar to Fig. 2, ex cept that it shows the carriagebeing arrested by the cooperation oi' the stops. Fig. Lt is adiagrammatic rear view showing' all but the lirst ot thecolumn-selective keys held in the ineffective position shown in Fig. 2.Fig. is a view similar to Fig. el, showingl the last column-stop keylever moving to a position where a decimal stop operated will arrest thecarriage.

'llhe llxnflerwood typewritingn machine comprises a carriage l which isdrawn along on rails (not shown herein) by a springI barrel 2;.saidspring is normally held from drawing the carriage along by means ot anescapeinent wheel 3, said Wheel cooperating with dogs (not shown herein)operated in any ordinary or desired manner from the character keys (alsonot shown herein). tiaid escapement wheel 3 is connected to a pinion. tworking` in a rack 5, said rack beingr pivoted on the carriage at 6 inthe usual manner in such 'a way that it may be swung upward clear oitthe pinion 4, in which condition the typewriter carriage4 is drawn alongfreely by spring barrel 2. For arresting the typewriter carriage when sodrawn along freely, there is provided a plurality ot tabulating keysforming two groups, one group comprising decimal keys l and the othergroup comprising column-selecting keys 8. Vlf'henever a decimal key 7 isdepressed, its key lever swings around a pivot l() so as to raiseupwardly a plunger titi uli

l11, the top of which plunger forms a counter-sto 12 which, whenprojected into the path ofp a stop 13 on the typewriter carriage, willarrest said carriage. When a decimal tabulating key 7 is thus depressed,it releases the carriage from the escapement mechanism; and for thispurpose, each plunger 11 is provided with a shoulder 14, said shouldersunderlying a universal bar 15 fast on a rock shaft 16, which rock shaftcarries a rock arm 17 having pivoted thereto a link 18. The downwardmovement of said lilik 18, whenever a decimal tabulating key isdepressed, swings a pivoted lever 19 so that a roll 20 on the endthereof underlying the rack 5, lifts said rack clear of the pinion 4,thus releasing the carriage, as above described.

In the form of the invention herein illustrated, the stops 13 on thecarriage are normally held so that their paths of movementl lie clear ofthe counter-stops 12; but, by operation of the column-selecting keys,any selected stop 13 may be swung, till its path will strike thecounter-stop 12, and so will arrest the carriage. To bring this about,the rack bar 21 on which said stops 13 are settable is pivoted at 22 toan extension 23 of the typewriter carriage, and is normally swungupwardly around said pivot by means of a spring 24.

The rack bar 21 may be swung downwardly around its pivot 22 by means ofany column-selecting key 8. Said columnselecting keys 8 (except thefirst) are, however, normally prevented from being depressed by'means ofa selector bar 25 which overlies their rear ends, the key levers 26 ofsaid column-selecting keys 8 being pivoted at 27. This selector bar 25is moved by the typewriter carriage so as to allow the column-selectingkeys to be operated at I times which may be determined by the stops 13set on the rack bar 21. To bring this about, the selector bar 25 isslidable in guides 28, and said selector bar, when moved along,successively brings a notch 29 in its lower portion over the levers ofthe column keys, as seen in Figs. 4 and 5. `When said notch 29 is overany key lever 26, it permits that lever to be operated thus swinging therack bar 21 downwardly so that the stops 13 thereon will strike anyprojected counterstop 12. To do this, the key lever 26 moves upwardly auniversal bar 30, so that'a link 31 attached to said universal bar willswing upwardly a rockarm 32, thereby depressing a rock arm so that aroller 34 on said last-named rock arm, which rides on an extension ofthe rack bar 21, will depress said rack bar, thus swinging the stops onsaid bar to a point where they will be intercepted by the counter-stops12 in the travel of the typewriter carriage.

rThe rock arms 32 and 33, it will be seen,

are fast on a shaft 35 whichis journaled on an extension 36 of thecasing carrying the decimal tabulating device. The universal bar 30 isguided in slots 44 at each end thereof, and is preferably provided witha link 31 at each end. For operating the selector bar 25, there isprovided thereon a rack 37 which meshes with a pinion 38 at the bottomof a shaft 39, said shaft carrying at its upper end a star wheel 40,which star wheel stands adjacent the rack bar 21 in such a position thatthe teeth of said star wheel are successively intercepted and turned bythe stops 13. The star wheel 40 and pinion 38 are so proportioned that,whenever one stop 13Y turns the star wheel 40 in passing it, it movesthe selector bar 25 the distance between the centers of two column keylevers 26, thus moving the edge of the notch 29 from one-column stop tothe neXt.

The star wheel 40 is preferably placed so that it will be turned by thestops 13 either before or after they reach the array of decimal stops12. As shown herein at Fig. 1, said star wheel is so placed that it willintercept the first stop 13 after said stop has passed all the decimalstops 12. l/Vith this construction the selector bar 25 should bearranged as shown at Fig. 4, in which figure the irst column key levercan be depressed at any time. Thus, to arrest the carriage in the firstcolumn, the first column key and the desired decimal key are depressed.When the typewriter carriage carries its first, stop 13 beyond thedecimal stops said stop turns the star wheel 40 and thereby moves theselector bar along bringing its notch above the various column keylevers successively and therefore releasing them as the successive stopsturn the star wheel. j f

From the aboveI description, it will be seen that to arrest thetypewriter carriage, the column key must be .held down when a decimalkey is depressed. The typewriter carriage will be released from itsescapement mechanism by the depressed decimal key and will travel alongfreely, turning the star wheel 40 as said star wheel is struck by thestops 13, until the desired column is reached. At this moment the notch29 in the selector bar 25 releases the column key lever which completesits operation by rising up at its rear end under the pressure of theoperatorsfinger, thus swinging down the rack bar 21 with its stops 13,so that said stops will be intercepted by the decimal stop 12 which hasbeen projected, and thus arrest the carriage.

In order to accurately space the columnselecting keys, they pass betweenthe teeth of a comb 41 ata point adjacent the selector bar 25.

The extension of the rack bar 21 which is engaged by the roller 34 maybe in the form of a bar 42 which overlies said rack bar, and is attachedthereto by means of brackets 43. Y

During the return ofthe carriage to position for Writing a neviT line,the column stops 13 rotate the star Wheel 40 backwardly and therebylreturn the selector bar 25 to normal position.

Variations may be resorted to Within the scope of the invention, andportions of the improvements may be used Without others.
